variables inside single quotes are not evaluated! This is the same variable:
echo $GLOBALS['var'];
$key='var'; echo $GLOBALS[$key];
With $GLOBALS['$key'] you refer to an invalid variable name $'$key'
PS: Output of
echo "GLOBALS['$key'] = $value<br>\n";
is right because $key is in double quotes (the outermost qoutes)

Actually I didn't. ;-) $GLOBALS[$key] is incorrect and depricated AFAIK. $GLOBALS['$key'] (with the single quotes) is the proper way to write these types of associative arrays/hashs. For shits and giggles however I tried your way and it made no difference to the code. Still didn't work right.-----Original Message----- From: Marek Kilimajer [mailto:kilimajer@webglobe.sk] Sent: Wednesday, March 26, 2003 1:16 PM To: Daevid Vincent Cc: php-general@lists.php.net Subject: Re: [PHP] What am I not understanding about $GLOBALS['myvar'] vs global $myvar?
